there are two ways:
1)
create a file % dd if=/dev/zero of=/home/init count=100000
then attach it to loop
losetup /dev/loop0 /home/init
then foemat it
mkfs.ext2 /dev/loop0
mount it
mount /dev/loop0 /mnt/test
copy files, unmount, and gzip ithe file
gzip /home/init
and copy it to /boot
(THIS WAY SOMETIMES CRASHES)
The best way:
2)
make a folder, (let it be /home/test)
copy files there

run
cd /home/test ; find . | cpio --quiet --dereference -o -H newc | gzip -9 /img.cpio.gz
this will create your image in /img.cpio.gz
(this one works)
_________________
gentoo never dies. If it doesnt work, do the most idiotic thing you can, and to prevent it from all unnessecary warnings use --force. This will break it, and while fixing, you will fix everything
(worked even when i deleted /sbin)
